Strap for Navitimer B01 Chronograph 46 Red Gold / Silver / Alligator

The Breitling Navitimer RB0137241G1P1 has a lug width of 24mm. This measurement refers to the internal distance between the two lugs at the point where the strap attaches to the case. It is a substantial width, proportionate to the 46mm case, requiring straps of solid construction and appropriate breadth.

For a Navitimer in 18-carat red gold, a vegetable-tanned alligator strap with a glossy finish is the most coherent choice: the block-scale texture and natural sheen complement the reflections of the precious metal. Alternatively, shell cordovan develops an organic patina over time that suits the character of this timepiece. On a 24mm lug, both options provide the structural integrity needed to support a 46mm case.

The Navitimer strap is secured by standard 24mm spring bars inserted into the case lugs. To replace the strap, use a fine-tipped spring bar tool: compress the spring bar, slide out the old strap, and insert the new one by seating one end of the bar in the lug first, then compressing the other end until it clicks into place. The operation takes a few minutes and requires no specialist equipment.

Yes. Any strap with a 24mm straight-end attachment is compatible with the Navitimer RB0137241G1P1. Milanostraps.it offers a curated selection of handcrafted 24mm straps — alligator, calf, shell cordovan, rubber — produced to the same proportions as the original Breitling strap. The buckle or deployant clasp should be chosen in yellow or rose gold to maintain visual consistency with the case.

Longevity depends on the material and frequency of wear. A quality vegetable-tanned alligator strap, properly maintained with non-aggressive conditioners and stored away from excessive humidity, typically lasts 3 to 5 years with regular daily use. Shell cordovan, being denser and more resilient, can exceed 5 years while developing a distinguished patina. Casati Milano straps carry an 18-month warranty against manufacturing defects.
